So far all is going well. I've installed Leopard on two of my Macs so far. On the MacBook Pro, all of my applications so far have worked well (the only one exception is a guitar training application called iPlay Music. I'll have to explore that, but otherwise, everything looks great. On my Mac Mini, I had just one little hiccup, which was that there wasn't enough space to load the new OS, and I only checked once I was already into the installation (my mistake). So, I had to quit the installation, and go back to delete some files from the Mac (using Tiger, which was still there, and presented to me as bootable disk. After I cleared away some space (deleted some redundant music files), I went back to the Leopard install (following the same procedures as before - regular upgrade - and it worked fine. I now have two growling machines. :-)
